The very POWERFUL the Solar Irradiated planet surface Rotational Warming Phenomenon: ( N*cp )1/16

Written by Christos I. Vournas,

M.sc. mechanical engineer

We do planets and moons surface temperatures comparison.


The presence of atmosphere doesn't  warm Earth's surface.

It is the other reasons, not the presence of atmosphere, that make Earth warmer than the Moon by +68°C.

Key words:


Specular Reflection


Φ - Solar Irradiation Accepting Factor (spherical shape and surface roughness coefficient), for smooth bodies Φ = 0,47 and for rough / porous Φ = 1


Immediate IR Emission

Planet 5261 Eureka’s ( Mars’ Trojan ) Mean Surface Temperature Tmean Equation

Tmean.eureka

(1/R²) = (1/1,524²) = 1/2,32

Eureka has 2,32 times less solar irradiation intensity than Earth has

Eureka’s albedo: aeureka = 0,39 geom. ( not bond )

N = (24h /2,6902h) rotations/per day, Eureka completes one rotation around its axis in 2,6902 hours (0,11209 day)

Eureka is a rocky planet, Eureka’s surface irradiation accepting factor: Φeureka = 0,47

cp.eureka = 0,203cal/gr oC, on Eureka’s surface is rock

β = 150 days*gr*oC/rotation*cal – it is a Rotating Planet Surface Solar Irradiation INTERACTING-Emitting Universal Law constant

σ = 5,67*10⁻⁸ W/m²K⁴, the Stefan-Boltzmann constant

Eureka’s Mean Surface Temperature Equation is:

Tmean.eureka = [ Φ (1-a) So (1/R²) (β*N*cp)¹∕ ⁴ /4σ ]¹∕ ⁴

Tmean.eureka = [ 0,47 (1-0,39) 1.362 W/m²*(1/2,32)*[150*(24h /2,6902h)*0,203 ]¹∕ ⁴ /4*5,67*10⁻⁸ W/m²K⁴ ]¹∕ ⁴ =

Tmean.eureka = 234,28 K

Tsat. eureka ~ 250 K.

The faster a planet rotates (n2>n1) the higher is the planet’s average (mean) temperature T↑mean:

Tmin↑→ T↑mean ← T↓max
